There are two versions of the Tuxedo card. The 'pay as you go' version doesn't charge a monthly fee but you pay between 50p and �1.50 every time you make a purchase. The other card doesn't charge you anything for making purchases but carries a �4.99 monthly fee. Both cards cost �9.99 to acquire.
There are plenty of alternatives. Which one is best for you will depend upon your personal spending pattern. Read this for general information about the way that the cards work:
